Problems with ssl

when I try to configure a SSL-site ISPConfig always makes a vhost.err-file. When I rename that file and try to restart apache I always get a fail from apache.
But there is nothing in the error.log, a syntax-check comes back clean.

Most likely the ssl cert is broken. Try to create a new one for this website trogh the ispconfug interface, Dont use any special chars for the info fields when you create the ssl certs as they might cause corrupt certificates.
